RE: Question - Form Validation
Noel, Thanks for the offer. I wanted to respond sooner - but email was down : ( The rush is definitely there, but my employer realizes the importance of getting it done right, so they are being patient. I think I am making some progress - I have found some resources on the subject. Currently the action of my form calls a controller JSP page. This page uses a Bean that I created. The bean uses the same fields as the form and performs all the validation. The controller JSP checks if validate then forward to processing page, else retry. I have written all the code for the form validation and will be testing it today. I will be posting if I run into any problems. Hopefully your offer still stands if it comes down to that :) Denise Mangano Help Desk Analyst Complus Data Innovations, Inc. -Original Message- From: Noel J.

RE: Question - Form Validation
Thanks for the tip...didn't know anything about them. I found that FormProc package while investigating Jakarta Regexp. As an aside, is there a need for Regexp or ORO now that J2SE 1.4 has java.util.regex? I'm no regexp guru by any means, I'm just curious. My development skills are bad enough without having to worry about keeping track of packages/libraries that aren't part of J2SE/J2EE.

RE: Question - Form Validation
your general concept here: validate page parameters is valid - redirect to processing page display form display default values for fields display form hints for invalid data if you don't have time to learn/implement this you might want to consider outsourcing your problem. typically one would use a tag library to do this. -Jason Pyeron -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron http://www.pyerotechnics.com - - Owner Lead Pyerotechnics Development, Inc. - - +1 410 808 6646 (c) 500 West University Parkway #1S - - +1 410 467 2266 (f) Baltimore, Maryland 21210-3253 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.

Re: Question - Form Validation
Denise, Consider using the Jakarta Struts project. It is very popular and provides a framework for form validation and error handling. http://jakarta.apache.org/struts/ Gary Denise Mangano wrote: Hi all :) I'm not sure if these types of questions belong is this list?? I've seen people post JSP and/or servlet questions, so I am assuming they do... ? I am trying to figure the best way to do form validation with JSP. I have a JSP with a form that calls another JSP to process that form and display the result. I would like to add an intermediary page that displays all the user input before the information is processed. Before I get to this intermediary page I want to make sure all fields are filled out and each field fits the format it should be. If a field is missing or incorrect, I would like the same page to be reloaded, with red text next to the field that needs to be corrected. Just wondering if anyone had any suggestions of the best way to handle this.
